Note from Tracy (December 2012):
"I saw that 'Shafer' wineries wine is not on your list and just checked their website. It is indeed vegan friendly. Here's the link directly to the FAQ's page that states it's vegan friendly: http://www.shafervineyards.com/faqs/index.php"

Website states, "Are Shafer wines vegan?
Yes. At no point in production do they come in contact with any animal products."
